Benefits of technology

The present invention provides an arterial occlusion catheter system with an occluding member, an atraumatic guiding tip, and a pressure accumulator. The atraumatic guiding tip eliminates the need for a guide wire, allowing for field operations without the need for fluoroscopy or other imaging modalities. The technical effects include improved safety and ease of use in arterial occlusion procedures.

Problems solved by technology

It is known that transient hypertension is a risk factor in arterial occlusion, particularly aortic occlusion.
Transient hypertension occurs when the blood pressure upstream the occlusion site rises to a potentially unsafe level during the time duration of the occlusion.
Thus, arterial occlusion carries with it two twin risks, hypertension during the occlusion and hypotension as the occlusion is withdrawn and blood flow restored, that must be managed.

first embodiment

[0183]In general, the alternative embodiment described herein with reference to FIGS. 12-18 includes the stiffener member 530, preferably the solid wire, instead of a tube with a lumen. The solid stiffener member 530 may be implemented as a solid flexible wire made of any suitable material that may be formed into a wire-like component. Examples of materials that may be used include polymeric materials, biocompatible metals, nitinol and stainless steel. The stiffener member 530 of this preferred embodiment may be constructed of a solid nitinol hypotube. The nitinol hypotube stiffener member 530 provides flexibility and sufficient stiffness along the longitudinal axis 531 and is generally a small diameter tube or wire. The stiffener member 530 implementation without a lumen removes the fluid communication with a third lumen. The stiffener member 530 does, however, allow for the implementation of a catheter system having a lower profile than the catheter system 100.

second embodiment

[0271]Referring to FIG. 41, a preferred second embodiment of an inflation control system 1550 is useful in the preferred inflation method of the present invention. A conventional balloon inflation device 1562 is illustrated in FIG. 41 (such as a QL Inflation Device, Atrion Medical, Arab, Ala). The inflation device 1562 has a fluid chamber and a plunger 1564. The plunger 1564 is preferably threaded to allow for rotation of the plunger 1564 relative to the fluid chamber and controlled depression of the plunger 1564 within the fluid chamber. A fluid conduit 1563 communicates with an outlet 1561 in the inflation device 1562 to communicate the inflation fluid to the occlusion catheter (not shown), such as the occlusion catheter system 100 of the first preferred embodiment or any of the other preferred occlusion systems described herein, that is coupled to the inflation device 1550 via a coupling 1561. A pressure sensor 1560 is preferably provided in the outlet line of the inflation devic...

Abstract

An occlusion catheter system includes a proximal hub having an inflation connection port and an inflation pathway. An inflation catheter member is connected to the proximal hub and has an inflation lumen. A stiffener member defines a longitudinal axis. The proximal end of the stiffener member is connected to the proximal hub. The stiffener member extends through a portion of the inflation lumen. An occlusion balloon has a proximal balloon end and a distal balloon end. A distal catheter member is positioned substantially on the longitudinal axis and is connected to the distal end of the stiffener member. An atraumatic tip is positioned on a distal end of the distal catheter member. The atraumatic tip has a substantially circular profile in a relaxed configuration. A pressure sensor is connected to the occlusion catheter system distally relative to the occlusion balloon and is connected to a processor by electrical wiring.
